Abstract

The 7.6(5) eV nuclear magnetic-dipole transition in a single Th3+229 ion may provide the foundation for an optical clock of superb accuracy. A virtual clock transition composed of stretched states within the 5F5/2 electronic ground level of both nuclear ground and isomeric manifolds is proposed. It is shown to offer unprecedented systematic shift suppression, allowing for clock performance with a total fractional inaccuracy approaching 1×1019.

Nuclear Clocks

Published 22 March 2012

An updated proposal for a clock based on the excited states of a nucleus could keep time better than existing clocks that use electronic states.
